Brent crude futures retreated in session trading as the United States expanded sanctions relief on Iranian oil exports, effectively allowing a broader range of international buyers, including US refiners, to purchase and pay for Iranian crude.
The policy shift signals a tangible increase in available global supply, countering the risk premium that had supported energy prices in recent weeks.
The market reaction reflects a rapid repricing of supply constraints.
Traders are adjusting positions to account for the potential influx of Iranian barrels into global markets, which could dampen price momentum.
This move follows a period of volatility where Brent had climbed on fears of restricted flows, but the latest diplomatic development has shifted sentiment toward supply adequacy.
The expansion of exemptions marks a significant pivot in US energy policy toward Iran, moving from restrictive measures to a more permissive stance that facilitates trade.
